Setting white balance on digital SLR camera

Cambridge SoundWorks Oontz XL sells both with and without speakerphone capability for $199 and $149, respectively.

Question: I have been photographing my daughter's gymnastics tournaments with my new digital SLR. The tournaments are held indoors under artificial light.

All of my pictures have a slight color cast from the artificial light. I have tried different white balance settings, including automatic white balance, but none of them seem to give me proper color. How can I correct this? - D.N., Washing-ton, Pa.

Answer: You are on the right track changing the white balance, but you need to be more precise than the camera's white balance presets will allow.

Bring a sheet of plain white paper or white posterboard to the next tournament. When you are inside under the artificial light take a picture of the white card or paper, using the zoom to fill the frame 100 percent so the image is completely of the white surface. The image does not have to be in focus as you are just capturing the color.

Look in your camera's menus for manually-set white balance. There will be a setting where you use an image to set the white balance. Select the image of the white sheet and use it to set the white balance. You will see the color cast disappear from the image and subsequent pictures will have the proper color balance. Don't forget to change the white balance setting back to the usual setting when you leave the event.

This technique works very well for photographing portraits in the shade as it will render proper skin tones, or anytime you want to be sure your colors are just right. I use it with my digital SLRs when I use large flash units in my studio, setting the white balance using the white background.

Final CES recap

My last bit of coverage from CES is about Cambridge SoundWorks, maker of the $69 Oontz Bluetooth speaker I have highly recommended. Cambridge SoundWorks told me they would have some new products on display in their private meeting rooms, but I was completely unprepared for the sheer number of new products they are developing.

First there was the Oontz XL, or "big Oontz" as they liked to call it. As you may have already guessed the Oontz XL is a super-sized version of the Oontz with more bass and louder volume. It will sell both with and without speakerphone capability for $199 and $149, respectively. I also was impressed with the various TV soundbars they had on display. One of them would more aptly be called a "soundbrick" as it was approximately 6 inches long yet provided loud, room-filling sound when paired up with the included wireless subwoofer. That is a really great idea. Who says a soundbar has to be almost as long as the television? They also had a very interesting combination of a bedside LED reading lamp and a Bluetooth speaker, and a larger boom-box like system with an iPod dock that sounded phenomenal, almost like a good quality component system.

In fact, if there was one common theme among all their new products it was that they all had the kind of good sound that catches you up in the music and gets your toes tapping. It goes to show their designers have good ears and the Oontz is not likely to be a one-hit wonder.
